Embodiments of the invention provide a slider structure able to lower a flying height compensation ratio caused by a projecting deformation of an air bearing surface of a slider by a flying height control mechanism and afford a change in flying height with a low control power. In one embodiment, a slider is provided with a leading edge, an air bearing surface, and a trailing edge. The air bearing surface includes a front pad, the front pad being made up of a front step bearing surface, leading rail surfaces, and side step bearing surfaces. The air bearing surface also includes a negative pressure groove surface surrounded by the front pad. The air bearing surface further includes a rear pad, the rear pad being made up of a rear step bearing surface formed at the same depth as the depth of the front step bearing surface and positioned on the trailing edge side, a trailing rail surface, an intermediate groove deeper than the trailing rail surface, and a trailing pad surface lying at the same height as the trailing rail surface. The front and both sides of the trailing pad surface are surrounded by the trailing rail surface.
A magnetic head slider comprising a leading edge, an air bearing surface, and a trailing edge, said air bearing surface comprising a leading rail surface formed on a leading edge side, a leading-side step bearing surface formed between said leading edge and said leading rail surface, a trailing pad surface formed on said trailing edge side and having a magnetic transducer integral with a flying height control mechanism, a trailing rail surface formed on both sides of said trailing pad surface along said trailing edge, a trailing-side step bearing surface formed on said leading edge side of said trailing rail surface, and a deep groove surface formed between said leading rail surface and said trailing rail surface, said deep groove surface being deeper than each of said step bearing surfaces, and each of said step bearing surfaces being deeper than each of said rail surfaces and said pad surface,
A magnetic head slider comprising a leading edge, an air bearing surface, and a trailing edge, said air bearing surface comprising a leading rail surface formed on a leading edge side, a leading- side step bearing surface formed between said leading edge and said leading rail surface, a trailing pad surface formed on said trailing edge side and having a magnetic transducer integral with a flying height control mechanism, a trailing rail surface formed on both sides of said trailing pad surface along said trailing edge, a trailing-side step bearing surface formed on said leading edge side of said trailing rail surface, and a deep groove surface formed between said leading rail surface and said trailing rail surface, said deep groove surface being deeper than each of said step bearing surfaces, and each of said step bearing surfaces being deeper than each of said rail surfaces and said pad surface,
A magnetic head slider comprising a leading edge, an air bearing surface, and a trailing edge, said air bearing surface comprising a leading rail surface formed on a leading edge side, a leading-side step bearing surface formed between said leading edge and said leading rail surface, a trailing pad surface formed on said trailing edge side and having a magnetic transducer which incorporates a flying height control mechanism, a trailing rail surface formed on the leading edge side and both sides of said trailing pad surface, a trailing- side step bearing surface formed on the leading edge side of said trailing rail surface, and a deep groove surface formed between said leading rail surface and said trailing rail surface,
